BATTERY CONNECTION.

-zen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Battery Gonnections, of which the following is a full,

clear, and exact description, such as will enable others skilled in the .art to which it appertains to make and use the same.

This invention relates to -electrical connections.

One of the objects thereof isto provide anelectrical connection of durable construction .and efiicient action;

Another object is to-provide a practical and cheap connection for storage-batteries which will reliably meet'thehardest conditions of use and offer a low electrical resistance.

Other objects will bein-part obvious and -in;-part pointed out hereinafter. The invention accordingly consists 1n the features of construction, combinations of elements .andarrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing, inwhich is shown one of various possible embodiv nents of this invention, Figure 1 is a side elevationthereof, partially 1n section along the line a-a, Fig. 2; Fig. 2 is an end view.

of the parts shown in Fig. 1; and Fig. 3 is a detail elevation showing one of, the

parts removed from Fig. 1 .upon a smaller .scale.

Similar reference characters refer to similar parts-throughout the "several views of the drawing.

, Referrlng now viding an end plate 2 which is provided The term electrical terminal portionofsthe battery. Fitted to this projection,'by means of a a lead casting. This member is provide with the spaced laterally extending arms 6 which rest uponthe cell and are Specification of Letters Patent.

to Fig. 1 of the drawing, there is shown a storage-battery cell 1, pro- Patented Sept. 1, 1914.

held in position,"-as'; by the screws 7. Connection5 terminates in a lug 8, within whichv is positioned an insert 9 ofrelatively hard metal,- as copper, which extends into-the body of the connection,-as at 10. Theinsert 9 and adjacent portions of the lug 8. are shaped to provide a tapering recess 11, which may extend in any desired direction.

'By the tapered-connection with the end plate of the cell, a close firm contact may be secured, even before the connecting member is burned in position, and the spaced arms 6 serve to prevent this connection from working loose or tending to rock or bend the end plate, even when the connection is provided, as hereinafter described, with a conductor, and even though the battery be mounted upon a railway carriage or motor vehicle and subjected to the most severe jarring and vibration.

A suitable conductor 12 is mechanically and electrically connected with a socket 13, provided with a tapering plug- 14: adapted torest within therecess 11. This plug is of such length that it -extends beyond the larger end of recess 11, evenwhen tightly fitted .in position, and is drawn into an intimate contact by means of a screw 15, tapped within its free end and bearing against the adjacent surfaces of the lug 8 through a washer 16. v H V The action of this apparatus may be to a large extent clear from the above, but it maybe noted that the hard insert 9 furnishes a bearing surface for the removable plug, which will permit the latter to be drawn tightly into position without undue wear and which will preserve a smooth surface for contact. The plug, moreover, is

readily connected or disconnected, and the though readily detachable, the plug when in position acts virtually as a portion of the connecting member 5, and the latter is securely braced by its lateral arms 6, as above described, and is thus well adapted to with- I stand any swaying of the connecting con-v vention could be made without departing,

from the scope thereof it is intended that all matter contained in the above description or'shown in the accompanying drawing shall be interpreted as illustrativeand not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

Having described my invention, hat I claim as new anddesire to secure by Letters Patent is:

1. In apparatus of the class described, in combination, a battery cell having an end plate, a metallic connecting member secured to said end plate and provided with a supporting arm diverging therefrom in rigid relation thereto and resting against said cell, and a conductor secured to said connecting member independently of said supporting arm. 7

2. In apparatus of the class described, in combination, a battery cell having an end plate, a metallic connecting member secured to said end plate and provided with a pair of spaced arms resting against said. cell, and a I(gonductor secured to said connecting mem- 3. In apparatus of the class described, in combination, a battery cell having an end plate, a metallic, connecting member secured to said end plate and provided with a pair of transversely extending relatively spaced arms resting against said cell and adaptedto support said member against rocking, and g conductor secured to said connecting mem- 4. In apparatus of the class described, in

combination, a battery plate, a connecting member secured thereto having a recess therein, and an insertion of relatively hard metal exposed in the inner walls of said recess, and a conductor secured Within said recess and fitting against said hard metal.

5. I apparatus of'the class described, in combination, a battery end plate having a tapered project-ion, a metallic connectlng member having a recess into which said projection fits and is permanently secured and a second recess, said member comprising an insert of relatively hard metal'exposed in the inner walls of said second recess, and. a

conductor secured within said second recess and resting'against said hard metal.

6. In apparatus of the class-described, in

combination, a battery plate, a connecting metal exposed in the inner walls of said recess, 'a conductor having a tapered portion fitted within said recess in contact with said hard metal, means connected with said tapered portion and extending through and beyond said recess and means coacting therewith to seal the end of said 'recess'through the other having a tapering projection removably fitting in said recess and said member connected with said battery hav ng a relatively hard metallic insert positloned and 'exposed to bear against the coacting portion of said other member.

8. In apparatus of the class described 1n combination, a storage battery, a conductor leading .irom said battery a metallic member secured to and electrically connected to a portion of said battery independently of said conductor and having a taperlng recess therein, a member secured to said conductor and fitting within said recess, and
